Testolone (RAD140) is the newest SARM, and the first official study reporting the discovery of this compound was published in 2010. Consequently, investigations made on RAD140 are scarce, so we can only rely on them and user reports. Interestingly, the name of this SARM comes from the company name that is developing it – Radius Health.
Testolone has a selective mode of action, which allows it to have anabolic effects without the side effects usually seen with anabolic androgenic steroids (AAS). These side effects include prostate enlargement, suppression of natural testosterone production, head hair loss, and many others.
This means that RAD140 interacts almost exclusively with the androgenic receptors in the muscle tissues and bones, but it does not activate these receptors in other parts of the body. As a result, we get pronounced anabolic effects, but without side effects and suppression, which opens new possibilities for medical applications of this compound instead of testosterone.
What’s more, due to the selective mode of action, RAD140 is safe for females too, since it will not cause virilization, or clitoris enlargement.
Note; dosage information is only for scientific reference purposes. SARMs Central, does not condone the human consumption or use of this substance outside of a controlled scientific environment (i.e. a lab).
The recommended dosages of RAD140 vary from 20 to 30 milligrams (mgs) per day, and the optimal cycle duration is 12-14 weeks.
As a research chemical, RAD140 should come in liquid form to be taken orally. It is important to drop the liquid directly into the mouth, as it may stick to the walls of the glass if mixed with liquids. After dropping it into the mouth, you can chase it down with water or grape juice. Due to the relatively long half life, RAD140 can be dosed just once per day, and there is no need to be taking it several times per day.
Testolone can render incredible benefits to an athlete without the cost of prominent side effects seen with anabolic androgenic steroids. Particularly, testolone will drastically improve one’s endurance and recovery, which will further lead to a considerable increase in muscle mass and strength.
Consequently, RAD140 will be a great addition to any sort of cycle, where it will give all of these qualities without any additional side effects. Besides, it can be successfully used solo in a long cycle, since it causes no suppression.
Potential Side Effects
One of the most appealing aspects of RAD140, and all of the SARMS in general, is the absence of side effects, making them some of the safest performance enhancing drugs (PED) these days.
As mentioned above, RAD140 will not cause suppression, nor will it cause any of the side effects commonly associated to steroids. What’s more, in spite of being oral compounds, SARMS are not liver toxic, and so is RAD140.
Finally, testolone does not interact with the aromatase enzyme, so there will be no estrogenic side effects when using it as a stand-alone PED, or with other non-aromatizing compounds.
